Junior ADU
Junior ADUs (JADUs)

- A separate entrance and efficiency kitchen
- Layouts that keep the rest of your home intact
- Streamlined permitting for the JADU path
- Bilingual guidance from start to finish
When do you need this service?

- You have a spare bedroom or attached garage to convert
- You want to house family without a full build

What do homeowners ask about Junior ADU?
What makes a JADU different from a regular ADU?
A JADU is built inside your existing home, capped at 500 square feet, with an efficiency kitchen. It permits faster and costs less, but it is smaller than a standard ADU.
Can I add a JADU and a detached ADU?
Many lots can have both a JADU and a separate ADU. Feasibility confirms what your specific property and city allow.

Where do we offer Junior ADU in San Diego County?
We provide junior adu in every city and community in San Diego County. Pick your city for local notes and service specifics.
Central Junior ADU in San Diego San Diego's neighborhoods range from century-old craftsman bungalows in North Park and Mission Hills to mid-century tracts in Clairemont and Bay Park, most sitting on lots with real room to build. Rental demand here is among the highest in the state, and ADUs give homeowners a direct way to generate income or bring family home without leaving the city.
North Coastal Junior ADU in Oceanside Oceanside's housing stock runs about 45 years old on average, meaning most lots in neighborhoods like Fire Mountain and Rancho Del Oro carry the kind of square footage where a detached ADU fits without feeling cramped. The marine layer keeps the climate mild year-round, which makes new ADU construction comfortable to live in and easy to rent out every month of the year.
North Coastal Junior ADU in Carlsbad Carlsbad's housing mix of older beach bungalows near the Village and 35-year-old master-planned homes in La Costa and Aviara gives homeowners real options for ADUs, whether that's a detached backyard cottage or a garage conversion. With a median home value near $1.4M and steady rental demand from families, professionals, and LEGOLAND-area visitors, the numbers on an ADU pencil out faster here than in most of San Diego County.
North Coastal Junior ADU in Encinitas Encinitas homes sit on lots shaped by decades of coastal living, many 45 to 60+ years old, which means there's often real space for a backyard or attached ADU without touching the street presence neighbors expect. The city's mix of surf-culture bungalows and larger Olivenhain parcels creates a wide range of ADU types that actually fit here.
North County Inland Junior ADU in Vista Vista's older ranch-style neighborhoods, from Buena Creek to South Vista, sit on lots that are often big enough for a detached ADU but underused. Families here build ADUs to house parents, bring in rental income, or create space that grows with the household.
South County Junior ADU in Chula Vista Chula Vista's housing split tells the whole ADU story: the older west side, around Third Avenue and Hilltop Drive, sits on larger lots with 1960s-1980s ranch homes that have room to add a detached unit, while the master-planned east side in Otay Ranch and EastLake holds newer two-story homes where a garage conversion or attached junior ADU is often the smarter fit. Families here build ADUs to house parents, grown kids saving for a home of their own, and to offset one of the highest mortgage-to-income ratios in South County.
